FIELD: process engineering.
SUBSTANCE: flexible contact zone of device switch ends may deflect at overloads from end stop rearrangement path. Device is furnished with appliances to re-straighten contact zone from deflected position into definite position in the range of rotational angles between two end stops. Sprinkler has rotary control element and case fixed part with device for mechanical reversal of said control part.
EFFECT: protection against vandalism, higher reliability.
